Real-time diagnostics without software
Goal
The invention relates to a diagnostic device for checking the I/O logic or cell of a microchip for errors (SEU) and defects. The error detection is carried out permanently by innovative integrated digital architectures and monitors digital I/O units in real time, thus eliminating the need for time-consuming and error-prone software solutions. The patent-pending solution can be integrated into any digital chip design, regardless of the technology.
This invention is patent pending.
